The tyre lever is a metal rod with a curved end for removing or installing an outer tyre from a rim of a car or bicycle. For this operation, usually two or more pieces are inserted simultaneously in different places around the rim.
A small kink at the end can serve to secure the tyre lever behind a spoke. The metal lever has a flattened end, sometimes with a profile to provide more grip to the hands. Models for bicycles are smaller and may be paired with an alligator wrench. [MOT]
